A dynamic config allows you to use configuration parameters to control the behavior of your application in near real-time.

In the example below, the dynamic config called **localization** retrieves localized strings for users in different countries. Users in Spanish-speaking countries see Spanish strings, while users in French- and Korean-speaking countries see French and Korean strings.

A sample JSON payload for French speakers appears below.

The following tutorials show you how to perform common tasks with dynamic configs.

## Follow a dynamic config

You can follow a dynamic config to receive personal notifications when the config changes, the same way you follow feature gates and experiments. When someone updates a config you follow, Statsig notifies you by email, in the console, and in Slack if you've configured [personal Slack notifications](https://docs.statsig.com/integrations/slack#personal-notifications).

To follow a dynamic config:

1. Open the config in the Statsig console.
2. Select **Follow** (the star icon next to the config name).
3. To stop notifications, select **Unfollow**.

On the _Dynamic Configs_ list page, use the **Following** filter to show only configs you follow.
